Pumice and Concrete: Lightweight Insulating Concrete

It's the nature-given physical makeup of pumice—essentially a foamed stone—that gives pumice concrete both its light weight and insulative qualities. PUMICE CONCRETE (not to be confused with Pumice-Crete®) is composed of Portland cement, pumice rock,

The Pumice Store: Lightweight Concrete Aggregate

Concrete: Lightweight Aggregate PUMICE CONCRETE is composed of Portland cement, pumice stones, pumice sand, pumice powder (pozzolan), and water. Compared to standard concrete, pumice concrete offers roughly a one-third reduction in weight and four times the r-value.

The Pumice Store: Lightweight Aggregate for Concrete

At Hess Pumice, we field scores of inquiries each NCCC season about sourcing our lightweight pumice aggregate and natural pozzolans. We added this page on the Pumice Store to expedite and streamline the process of getting concrete canoe teams the lightweight aggregate they need to build a winner.

MIX DESIGN OF LIGHTWEIGHT SELF-CONSOLIDATING CONCRETE

Pumice is a volcanic aggregate that has been used to produce lightweight concrete for many years. In New Zealand there are large deposits of pumice in the central North Island. Self consolidating concrete was introduced into Japan in the late 1980s due to a shortage of skilled workers.

(PDF) Development of Lightweight concrete for structural

Pumice lightweight aggregate (PLA) is a volcanic-origin natural aggregate of very low specific gravity. It is possible to develop light weight concrete of density up to 1450 kg/m 3 using pumice...

Pumice and Concrete: Applications and Benefits of Pumice

Pumice-Crete® is a low density, lightweight, low-rise structural concrete using 3/8 pumice aggregate, Portland cement, and water. The honeycomb-like walls are formed and poured at a typical thickness of 18-24 inches, with no additional structural reinforcement [ 03] or insulation needed.

Lightweight Precast Concrete for Commerial & Residential

Litecrete lightweight precast concrete is manufactured using local pumice aggregate. The pumice provides both in-built insulation and a 40% weight reduction compared to standard precast concrete. The product can be used in both residential and commercial construction. We don’t get involved in building ourselves; we simply manufacture and supply the panels to architects’ and engineers

Lightweight Concrete: Types, Properties, Merits & Demerits

Introduction to lightweight concrete: Light concrete is made of lightweight aggregate, it is also called foam concrete. Since this cement consists of lightweight aggregates, it is used in coarse aggregates and sand, clay, foamy slag, clinker, and crushed stone, aggregates of organic and inorganic.. This concrete saves 15 to 20 % in the cost of construction of floors and roots.

Lightweight concrete incorporating pumice based

01/03/2011· Durability properties of lightweight pumice concrete. The durability characteristics in terms of drying shrinkage and water permeability of concrete mixtures are summarized in Table 6, Table 7. 3.4.1. Drying shrinkage. Aggregates with high absorption properties are associated with high shrinkage in concrete and this is confirmed from the increase of drying shrinkage with the increase of coarse

PUMICE AGGREGATES FOR STRUCTURAL LIGHTWEIGHT AND

lightweight concrete containing both partially saturated and fully saturated pumice aggregates. A vacuum saturation system was developed to completely saturate the normally partially saturated aggregates and consequently avoid a loss of workability attributed to the high absorption capacity of pumice. Shear strength and bond strength of pumice concrete was investigated, as well as the

Lightweight Concrete: Light weight aggregate concrete

Nowadays, structural lightweight concrete is a demanded material for construction, because a sufficient strength lightweight concrete used in conjunction with steel reinforcement is more economical than conventional concrete. A structural light weight concrete has strength in the range of: 28 days compressive strength greater than 17 MPa, and 28 days unit weight (air dry) less than 1850 Kg/m3

High Strength Natural Lightweight Aggregate Concrete

High strength lightweight aggregate concretes are usually produced using special artificial aggregates together with mineral and chemical admixtures. Using natural lightweight aggregates instead of processed artificial aggregates can significantly reduce cost of such concretes. Turkey has rich reserves of volcanic tuff and pumice stones. In Turkish standards highest strength classes for

Fibre Reinforced Light Weight Aggregate (Natural Pumice

concrete is achieved with 20 percent replacement of natural coarse . aggregate by. pumice aggregate and with 1.5 percent of fibber. Also with 40% pumice and with 0.5% of fibbers average target mean strength o. f M . 20 . concrete is achieved. The compressive strength of pumice concrete is seen to increase with the fiber content and reaches an

How to Make Concrete Lighter Hunker

Create lightweight concrete with pea-sized crushed pumice stones. Concrete is a strong and durable building material that, when properly mixed and placed, can last for decades with only minimal maintenance. One of the things that makes concrete so strong is the sand and gravel aggregate used in the mix. This rocky material naturally makes concrete heavy, limiting its transportation and use on

HIGH-STRENGTH STRUCTURAL LIGHTWEIGHT CONCRETE

Natural lightweight aggregates such as pumice [most widely used], scoria, volcanic cinders, tuff and diatomite. Or artificial aggregates or rotary kiln produced lightweight aggregates such as expanded clays, slates, slag, perlite or shale’s. Cenospheres [hollow sphere comprised largely of silica and alumina with cavities filled of inert gases such as nitrogen and carbon dioxide] and recycled

What is Lightweight Concrete? -Types, Uses and

Lightweight concrete mixture is made with a lightweight coarse aggregate and sometimes a portion or entire fine aggregates may be lightweight instead of normal aggregates. Structural lightweight concrete has an in-place density (unit weight) on the order of 90 to 115 lb / ft³ (1440 to 1840 kg/m³).
